Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB GDDR3		47 Watts
Radeon RX 570		150 Watts
	Difference: 103 Watts (219%)

Memory Bandwidth

In theory, the Radeon RX 570 should be 924% quicker than the GeForce 8600 GT 512MB GDDR3 in general, because of its greater bandwidth. (explain)

Radeon RX 570		229376 MB/sec
GeForce 8600 GT 512MB GDDR3		22400 MB/sec
	Difference: 206976 (924%)

Texel Rate

The Radeon RX 570 will be quite a bit (approximately 1630%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB GDDR3. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 8600 GT 512MB GDDR3		8640 Mtexels/sec
	Difference: 140864 (1630%)

Pixel Rate

The Radeon RX 570 will be quite a bit (more or less 765%) better at full screen anti-aliasing than the GeForce 8600 GT 512MB GDDR3, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 8600 GT 512MB GDDR3		4320 Mpixels/sec
	Difference: 33056 (765%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
